T0 (ZZZ whom it may concern:

Be it known that 1, PAUL Monnim, a citizen of Hungary, residing atElyria, in the county of Lorain and State of Ohio. have ,inventedcertain new and useful Improvements in Plows, of which the following isa specification.

This invention relates to certain new and useful improvements in plowsand has par ticular reference to aplow having the forward end of thecarrying beam therefor adjustably associated with a plate upon a wheeledcarriage whereby the plow beam may be reversely rotated for disposingthe plow zit-different inclinations or side hill and level ground work.

A further object of theinvention is to provide an adjustable plowmounting of the type above set forth that is operable from the handleend of the plow to permit the plowto be shifted to different angularpositions by the operator during the act of plow- TVith the above andother objects in view and others that will become apparent as the natureof the invention is better understood. the same consists of the novelform, combination and arrangement of parts hereinafter more fullydescribed, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designatecorresponding parts throughout the several views,

Figure 1 is aiside elevational view of a plow constructed in accordancewith the present invention, illustrating an angularly adjustable plowand operating means therefor terminating at the handle end of the p%owfor adjusting the angularity of the P 0W,

taken on line VII-VI of Fig. 3 showing the single latch pin andthree-hole adjustment therefor, and

Figure 7 is a horizontal sectional view taken on line VIIVII of Fig. 3.

The plow embodies a beam 1 that sup. ports a-plow 2 at the rear endthereof and with which beam rearwardly directed handle bars 3 areassociated while a wheeled carriage 4 carrying a draft clevis 5 isadjustably connected to the forward end of the plow beam 1 as shown inFigs. 1 and 2.

The adjustable connection between the plow beam 1 and carriage 4includes a disk plate 6 traversing the forward end of the plow beam- 1and spaced therefrom, the rear face of'the disk plate 6 carrying a pairof parallel strap members 7 having a plate 8 clamped therebetween andcentrally positioned by the spacing members 9 with the plate 8 retainedtherein by the securing bolts 10. The rear side edge of the plate 8 isstraddle by the rearwardly directed bi-.

furcated ends of the clamping plate 11 with the bifurcated ends boltedas at 12 to said clamping members 11 bolted as at 13 to the forwardendof the plow beam 1.

A disk plate 14 is associated with the disk 6 and is positionedforwardly thereof as illustrated and in flat engagement, the disk plates6 and 14 being pivotally connected by the pin 15 as clearly illustratedin Fig; *7 that is positioned axially thereof. The disk plate 14 isconnected to the wheeled carriage by the forwardly directed bracket arms16 projecting from the upper and lower edges of the disk plate 14 andterminating in a single extension 17 having a clevis connection 18 withthe wheeled carriage as clearly illustrated in Fig. 3. I

To retain'the disk plates 6 and 14 in adjusted positions and also foraccommodating relative movement thereof when it is desired to vary theangularity of the plow relative to the wheeled carriage, tensioned latchmechanism is associated with the two disk pivotally connected to thelink 21 directed toward the disk 14 and having associated with the freeend thereof a secondlink 22 that carries a latch pin 23, a coil spring24 being interposed between the link 21 and bracket 20 for normallyinfluencin g the latch pin 23 in a direction toward the disk 1 The disk14 has a single opening 24 to accommodate the passage of the latch pin23, and the disk plate 6 is provided with a series of openings 25 torthe selective reception or the latch pin. An angle bracket 26 extendsupwardly from the disk plate 14 and a curved lever 2. has a pin and slotconnection 28 with the upper end of said bracket, the forward lower endof the lever 27 being pivotally connected as at 29 to the forwardpivotal connection between the link members 19 and 21 while an operatingrod or flexible connection 30 extends between the rear end ot the lever27 and the operating hand grip 3i pivotally mounted as at 32 upon one ofthe handle bars The clevis connection 17-l8 provides for lateralswinging in vement of the plow 2 relative to the wheeled carriage 4: andwith the plow 2 vertically positioned relative to the carriage, thelatch pin 23 is positioned in one of the openings 25 in the disk plate6. When it is desired to dispose the plow 2 at an angle with respect tothe vertical axis of the wheeled carriage, the hand grip 31 is operatedto shift. the lever 27 and move the link members 19 and 21 against theten sion of the spring 24 to remove the latch pin 23 from the opening 25and by tilting the plow beam 1 and plow to either side, the latch pin 23is positioned to be received in one of the other openings 25 for lockingthe plow 2 in its angularly adjusted posi tion. The angular adjusting ofthe plow may be accomplished at any time either when the plow isstationary or in use and the latch pin connection between the diskplates 6 and 14 will effectively hold the plow djusted position.

hile there is herein shown and described the preferred embodiment oi?the present in vention, it is nevertheless to e understood that minorchanges may be made therein without departing from the spirit and scopeof the invention as claimed.

Vfhat is claimed as new is 1. In a device of the type described, a plowbeam, a plow carried thereby, handle bars associated therewith, awheeled carriage, and means for connecting the plow beam to the wheeledcarriage for permitting the disposing of the plow at diilerent angularpositions in respect to the wheeled carriage, said means including adisk plate connected to the plow beam, a second disk plate centrallyrotatably connected to the first mentioned disk plate, forwardlyconverging arms rigidly connected together at their outer ends and tothe second disk plate at their inner ends, means for connecting theouter ends of said arms to the wheeled carriage, means for a'djustablyconnecting said disk plates outwardly of their point of pivotalconnection, and means manually operable from the handle bars forcontrolling the last mentioned means.

2. In a device of the type described, a plow beam, a plow carriedthereby, handle bars associated therewith, a wheeled carriage, and meansfor connecting the plow beam to the wheeled carriage for permitting thearranging of the plow at difierent angular posh tions in respect to thewheeled carriage, said means including a disk plate connected to theplow beam, second disk plate centrally rotatably connected to the firstmentioned disk plate, means for connecting the second disk plate to thewheeled carriage, a bracket carried by the second disk plate, a curvedlever slidably pivotally connected to said bracket, a lever pivotallyconnected to the second disk plate and the curved lever, a linkconnected tothe curved lever, means carried by said link for selectivelyconnecting said disk plates at different positions in respect to eachother, resilient means for normally holding the last mentioned means inits operative position, and means for manually operating said curvedlever for permitting rotary movement of said disk plates in respect toeach other.

In testimony whereof I affix my signature.

PAUL MOLNAR.
